ARMOR OR SHI ELD FOR PNEUMATIC TIRES.

SPECIFICATION forming part of Letters Patent N 654,278, dated July 24, 1900.

Application filed December 7, 1899. Serial No. 739,517. No model-l T0 aZZ whom it may concern:

Be it known that LWILLIAM EDWARD PUGS- LEY, a citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in Armors or Shields for Pneumatic Tires; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to armors or shields for pneumatic tires, and more particularly to that class of inventions used in connection with a double-tube tire.

The objects of the invention are to provide a simple, durable, and inexpensive armor or shield which will be practically impenetrable and to make provision whereby the packing will be prevented from bunching or becoming displaced incident to the jars occasioned. by obstacles or obstructions in the roadways.

With these objects in view the invention consists in certain features of construction and combination of parts, which will be hereinafter set forth.

Referring to the drawings, in which like numerals of reference denote corresponding parts in both views, Figure 1 is a cross-sectional View taken through a tire, illustrating the application of my invention and Fig. 2 is a detail perspective View, in transverse section, of a portion of the shield or armor.

In the drawings, 1 denotes the outer tube, and 2 the inner tube, of a pneumatic tire.

3 denotes the armor or shield, which consists of two strips of material elastic longitudinallyand inelastic transversely. Arranged or packed between these strips is an impenetrable material preferably, but not necessarily, composed of raw cotton. In connecting the longitudinal side edges of the strips I prefer to stitch through the packing, so that in use the packing will not tend to bunch, which would be the case were it left free within the pocket formed by the strips. To serve as an additional means for preventing the bunching of the packing, I prefer to place between the layers of the packing an elastic ribbon 4. This, in connection with the material of which the strips are formed-namely, the material which will give longitudinally but not later= ally-greatly adds to the attainment of the objects in View and is considered an important feature of my invention.

I am aware that it is not new to provide a shield or armor for pneumatic tires in which a packing of cotton or like material is employed and is placed between the inner and outer tubes of the tire in a manner similar to my invention. I am, however, unaware of any patent showing the manner of connecting the packing to the shield and of making the shield of material elastic in a longitudinal direction and non-elastic in a-lateral'direction. Neither am I aware of a patent showing in addition to these features and in combination therewith an elastic strip interposed between the layers of packing.

What I claim is 1. An armor or shield for pneumatic tires, consisting of a casing elastic longitudinally and non-elastic laterally, anda packing of impenetrable material located within the casing.

2. An armor or shield for pneumatic tires, consisting of a casing elastic longitudinally and non-elastic laterally, and a packing of impenetrable material located Wi thin the casing, and strips of elastic material interposed between the layers of packing.

3. An armor or shield for pneumatic tires, consisting of a casing elastic longitudinally and non-elastic laterally, and apacking of impenetrable material located within the casing, and strips of elastic material interposed between the layers of packing; said packing being stitched to the casing along its marginal edges.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
